Ethereum air drop cheating
many new users believe that the sole purpose of mining is to generate ether in a way that does not require a central issuer (see our guide "what is ether?"). It's true. The token of Ethereum is proced in the process of mining, with a mining rate of 5 Ethereum coins per piece. But mining is at least as important. Usually, banks are responsible for keeping accurate records of transactions. They make sure that money is not created out of thin air and that users don't cheat and spend money many times. However, blockchain introces a new way to keep records, the whole network instead of intermediary, to verify transactions and add them to the public ledger
Ethereum mining
although "no trust" or "trust minimization" monetary system is the goal, there are still people who need to ensure the security of financial records and ensure that no one cheats. Mining is one of the innovations that makes decentralized records possible. Miners have reached a consensus on the history of transactions in terms of preventing fraud (especially double spending on ether) - an interesting issue that hasn't been addressed before the decentralized currency works on the blockchain. While Ethereum is looking at other ways to reach a consensus on the effectiveness of the deal, mining currently keeps the platform together
how mining works
today, the mining process of Ethereum is almost the same as that of bitcoin. For each transaction, the miner can use the computer to guess the answer repeatedly and quickly until one of them wins. More specifically, the miner will run the unique header metadata (including time stamp and software version) of the block through the hash function (which will return a fixed length, unordered string of numbers and letters, which appears to be random), changing only the 'nonce value', which will affect the hash value of the result
if the miner finds a hash that matches the current target, the miner will be granted ether and broadcast the block across the network for each node to verify and add to their own ledger . If miner B finds the hash, miner a stops working on the current block and repeats the process for the next block. It's hard for miners to cheat in this game. There is no way to fake the work and come up with the right answer to the puzzle. That's why solving puzzles is called "proof of work."
on the other hand, others have little time to verify whether the hash value is correct, which is exactly what each node does. About every 12-15 seconds, a miner finds a stone. If the miner starts to solve the puzzle faster or slower than this, the algorithm will automatically re adjust the difficulty of the problem so that the miner can rebound to about 12 seconds of solution time
miners earn these ethers randomly, and their profitability depends on their luck and the computing power they put in. The specific workload verification algorithm used by Ethereum is called "ethash", which aims to require more memory, making it difficult to mine with expensive ASIC. Special mining chips are now the only profitable way to mine bitcoin
in a sense, ethash may have achieved this goal successfully, because dedicated ASIC is not available for Ethereum (at least not yet). In addition, as Ethereum aims to shift from proof of work mining to "proof of equity" (which we will discuss below), buying ASIC may not be a wise choice because it may not prove useful for a long time< However, Ethereum may never need miners. Developers plan to abandon proof of work, the algorithm currently used by the network to determine which transactions are valid and protect them from tampering to support proof of equity, which is guaranteed by token owners. If and when the algorithm is launched, proof of equity can become a means to achieve distributed consensus, and the consensus uses less resources.

hope to adopt, thank you!
Ethereum protocol will be as simple as possible, even at the cost of some data storage and time inefficiency. An ordinary programmer can also perfectly implement the complete development instructions. This will ultimately help to rece the impact of any particular indivial or elite group on the agreement, and promote the application prospect of Ethereum as an open agreement for all. Optimizations that add complexity will not be accepted unless they provide very fundamental benefits.
The difference between medical insurance card and cash payment is as follows:
1
the medical insurance card is used to pay the bill. Cash settlement is to give cash directly
2
the medical insurance card can only be used when going to the designated hospital for medical treatment. There is no hospital requirement for cash settlement
The reimbursement process is differentreimbursement process of using medical insurance card: indivials do not need to pay first and then apply for reimbursement. Medical insurance and hospitals can directly settle the reimbursement part of medical insurance. Only when they settle accounts, the self paid part is paid by themselves with the balance of medical insurance card or cash
cash is all borne by indivials
extended data:
usage of medical insurance card:
1. Scope of medical insurance card: insured employees can swipe the card on POS machine with their password when they purchase medicine in designated hospitals and pharmacies, but they cannot withdraw cash or transfer money
2. Balance inquiry of medical insurance card: the insured employees can inquire about the balance by dialing the telephone, or at the Bank of China savings office or the designated hospitals and pharmacies in the urban area. You can also log in to the social security inquiry system online
3. Medical insurance card transaction inquiry: insured employees can print medical insurance card transaction records, including indivial account payment records and consumption records, with their ID card and medical insurance certificate. If you have any questions about the transaction records, you can go to the retail business department of BOC for inquiry
4. Password of medical insurance card: if the Insured Employee changes his password, he can dial the phone to change it, or he can go to the Bank of China savings office with his ID card to change it. If the Insured Employee forgets the password, he / she can report the loss of the original password to the Bank of China savings office with his / her ID card and change the password
5. Custody of medical insurance card: the insured employees should keep the medical insurance card properly. If they lose the card, they should immediately go to the unit to issue a certification letter and seal it at the medical insurance department for confirmation. Then they should report the loss to the Bank of China savings office with their ID card and go through the card replacement proceres. After 7 days, they can get a new card
